conclusions anesthetic and surgical management was difficult due to the inability to position in supine and rapidly progressing hemorrhagic shock. surgical management for extraction of this iron bar and intensive monitoring and resuscitation resulted in an uneventful successful outcome. introduction penetrating thoracoabdominal injuries are potentially life threatening due to the associated hem...

Refrigeration service personnel have used leak detection equipment for years when servicing refrigeration equipment. In the past, leak detection typically was only concerned with leak pinpointing, either with an ultrasonic device, soap bubbles, dyes, thermal conductivity, or other electronic devices. Today, refrigerant leak detectors exist not only for pinpointing leaks, but also for monitoring...

The aim of this article is to give an overview of recent developments in the field of general anesthesia monitoring. We measure different physiological signals related to the functioning of several nervous systems. Using statistical or signal processing methods, monitors are derived and correlated to the dosage of anesthetic agents and to the status of the patient. Comparisons among existing mo...

EVOKED potentials (EPs) are the electrophysiologic responses of the nervous system to sensory or motor stimulation. Stimulating the nervous system initiates the transmission of neural signals that may be recorded as EPs from various points along the stimulated pathway. Intraoperative monitoring (IOM) of EP has gained popularity because EPs reflect the functional integrity of neural pathways in ...

In this paper, we present an efficient complex event processing system tailored toward monitoring a large-scale setup of manufacturing equipment. In particular, the key challenge in the equipment monitoring is to develop an eventbased system for computing complex manufacturing queries coupled with event notifications and event and query result visualization components. Furthermore, we present a...

One area of biomedical instrumentation that is becoming increasingly familiar to the general public is that of patient monitoring. Here electronic equipment provides a continuous watch over the vital characteristics and parameters of the critically ill. In the coronary care and the intensive care units in the hospitals, thousands of lives have been saved in the recent years because of the caref...

This paper presents research regarding the monitoring of the brain and the adequacy of anesthesia during surgery. Particular variables are derived from EEG and ECG signals and are correlated to anesthetic gas (sevoflurane) concentration, in pediatric anesthesia. The methods used for parameter extraction are based on change detection theory and time-frequency representation. Preliminary results ...
